downwardly through the buck and into a receivin chamber 13 preferablylocated within t e bracket 5. The inlet 11 and outlet 12 are locatedremote from the passage connecting the chambers 7, 8, and delectors 12lare located near the passages 11, 12, to insure a complete distributionof the steam.

14 is a conduit, Figs. 4 and 7, communicating with the receiver 13- andopening into the chamber 9, said conduit bein located artly in the lowerbuck and part y in the racket 5. I

is a passage or conduit leading from the receiver 13 in the bracket 5.16, Fig. 1, is a valve casing, connecting the passages or conduits 14,15, in which casing, a suitable valve is located for controlling theflow of steam `to the chamber 9, this valve being operated by a rod 17extending downwardly to the base of the machine and actuated ashereinafter described.

The lower buck. is preferably cast in one piece so that no separate topor top plates are necessary, and hence machining and fitting of partsare avoided. As seen inFigs. 5, 6 and 7 the chambers 7, 8 graduallydeepen along the coursetaken by the steam from the inlet 11 to .theoutlet 12, the chamber 7 deepening' fromthe inlet 11 and the chamber 8deepening in the opposite direction toward the outlet 12, so that anywater appearing in saidv chambers will drain into the receiverf13. ,1Thettop of the chamber 9 is perforated at 18, Fig. 4, and a distributingplate or strip 9a overlies the perforations, and serves to distributethe steam ejected Afrom the perforations over the entlre effective'surface 'of the buck so that the steam paes thi-'0:5 h all portionsofthe arment being pr Fi 13'and 1 4. vaid strip/1s here illustrate asformed with a "lengthwise" corrugation 9F disposed over the to the4lengthwise edges of the distributing thev faces ofl' the Ff line ofperforatins and with transverse cor-V rugationsc, 'for Vfacilitating thedistribution ofthesteam. The transverse corrugations 9 lead from thelengthwise `corrugation 9" plateat angle thereto, and, consequently,

between s aced apart surgthwise e ges of the distributing plate andtheunderlying portion of. thelower'buck. vThe strip 9 is'secured to thebuck -ina'n'y suitable manner as b clenching its ends'fovfer. the ends'of thebuck Y 'but may be'secured to aw'ire gauze overlypadding 6?.

outlets for t e. bucks The steam. passes into the chamber 7 through theinlet conduit 11, along the chamber 7 throu h the passage 10 into thechamber 8, lengt wise of the chamber 8 through the outlet conduit 12, tothe receiver 13 where any water of condensation is deposited and carriedolf through the pipe 20; and when the rod 17 is operated to openvthevalve within the casin 16, the steam, from which the Water has geenremoved, passes through the passage 15, valve casing 16, and passa e 14to the central chamber 9, where 1t is e]ected through the rforations orjets 18. The steam in the c amber 9`is heated by the hot live steam inthe chambers 7, 8, so that condensing of the steam -in the chamber 9 andhence the ejection of Water through the perforations 18 is prevented. Asuitable deector 22 is located in the receiver 13, see Figs. 6 and 7,between the conduit 12 and the passage 15, this deflector causing thesteam to circulate in the receiver instead of being. permitted to passdirectly out of the passage 15 to the chamber 9. In use the receivingchamber remains partly filled with the water of condensation so that thesteam will not pass through the drain pipe but onthe contrary isWithdrawn through the passage 15 above the level of the 'water of'condensation. A

' The inlet pipe section 27 is connected to a feed pipe section 42 `andthe outlet pi section 28 to a pipe section 43 by a exib ej j. lly fromthe coupling 44 extending radia pivot 31 of thev frame lever 24. Y

This coupling 44 comprisesunions45, 46,

and side pieces 47 48 connecting the unions. f

located' at the axis of the' The union is l frame lever 24 and isprovided with radial `nipples 49, for 'receiving the pipes 42, .43

The side pieces 47, 48 are formedwith passages 61, 62 which connect.,res 'vely with the passages 51, 56, kand 52, 5 of the unions. The sidepieces are` c lani `d t0'- gether 'by'fsuitablebolts `63`1ocated` theunions 45, and 46. The pipe 43 is conf f nected to the inlet pne 191erthe lower buck y y to drain or and is also connecte laterally from'. h yto the thl'eev n l point suspension of the bul 23, and the arrangementof the bearings thereof, thev 'tudinal axis" rment aring wise i pipe 21through a valve 43 which is normally closed.

In operation the steam passes from the pipe 42 to the passage 51 andthrough the passages 51, 61, 56, and the pipe 27 into the chamber 25 ofthe upper buck, through the chamber 25, the passa e 26 and the chamber25* andi out throught e ipe 28 to the nipple 55, thence through t epassages 57, 62 and 52 to the return pipe`43, thence through the inletpipe 19 for the lower buck, assage 11, chambers 7,8 and passage 12 ofpthe lower buck, to Ithe receiver 13 where the water is deposited.' Uponthe opening of the valve in the chamber 16, the steam p e from thereceiver to the chamber 9, through l bucks, the entireutilized volume ofheating medium or steam passes successively through 'j both pressingelements-or bucks, and' all waf ter is,removed or reconverted into steambefore the steam reaches the Vjets 18.

The means for `operating the carriage 24 of the upper buck comprisesmitting parts including a yielding or spring connection` As hereillustrated said means comprises an angle lever 64 pivoted at 65 to theframe, near `the bottom thereof and formed with a forwardly1 extendingarm 64m provided with va suitable pedal 66, and with an upwardly andrearwardly extend ing arm 64, and a toggle link interposed between thelatter arm 64? and the rear arm of the frame lever 24, Said linkincluding the' yielding or spring power transmitting part. Preferably,this toggle link includes sections 67, 68, 69, andthespring means. Themem-y ber or section 67 is pivoted at 67 to the rear arm of the lever orcarriage 24; the member or section I6 8 is a shackle or clevis pivotedat 68* to the lever 64; and the member or section 69! is a' rod slidableendwisely of one Y ofthe sections 67, 68 as the section 68, and

,adjustable endwisely relatively` to 'the other section 6 7. The section69-ishere shown as a screw which threads intothe part 67 and imI slidesin the shackle 68, the slidin movement bein resisted bya spring 70, t escrew having a ead 71 engaglng the shackle to prevent detachment of thesection 69 from. the shackle. g f

The endwise adjustment of the section 69 relatively to the section y67to lengthen or shorten the toggle link, comprises means for the owertrans- Lacasse rotating the screw section 69, and means is hereillustrated as a nut 72 located on the screw 69 and locked in positionby a nut 73. The nut 72 also forms an abutment for'on'e end of thespring 70 which encircles 'the screw and abuts at its-other end againstthe shackle. Movement ofthe nut 72 on the *screw 69, afterthe lock nut73 is loosened,

adjusts the tension of the spring 70, and

turning of the nut 72 without loosening the nut 73, causes the screw 69to turn in the sectionf'l, and hence to lengthen or shorten the togglelink.

When the upper 'buck is down, the rearl arm of the frame lever 24 lis ina horizontal position as shown in Fig. 1, and the coil lspring 64", Fig.v1, connected to :the forward y extending renter line of the t ine, aswill .be presently described, by a counter weightj74 mounted on` thepivot 67l| and havin a pair.' of forwardly extending arms 75 w 'ch ressat their front ends against the under side of the web 32 of the frameleverv or carriage 24.' Owing to the spring 70, the toggle joint ispermitted to enter its kdead center line irrespective of the thicknesskof the garment or other article being ironed between the upper andlower bucks, and furthermore the machine, owing I i to. the spring 7 0,can be'adjusted to suit the strength ofthe operator, and the pressure ofthe upper buck can be regulated.

The movement ofthe toggle joint 68* out of the dead center line iseifected by means of a lever 76 pivoted at 77 to a suitable bracket 78and having one arm 79 thereof pressing against the under side of theforwardly extending arm 64, of thevlever 64. Obviously when the frontend of the lever 76 is depressed, the arm 79 will push upwardly on theforwardly extending arm 64a of the lever 64 causing the lever to move,so thatA the joint'68 ofthe toggle is carried rearwardly. The pedal 66at the front end of the lever 64 is a separate piece from the lever 64and is connected thereto so as to be adjustable upwardly and downwardlytherevon in any suitable manner, this adjustment is 'held in anyadjusted pivotalposition by a bolt 81 passing through said front arm ofthelever 64 and a slot 82 in the pedal 66, and also by a tooth 83 on thepedal coacting with one of a series of teeth 84 on the arm 64 of thelever 64. Y

A suitable pedal is connected to the rod 17 `aus `tl'ated as nuts 86ythreading :inthe framel.; The bearing-89 is preferof the link` 8,7'.v cv In operation the; machine'is arranged with theupper buck in its-.upperposition so that a ma be placed on the lower buck. e pedal-r k1s thendepressed bringi the "parts into theirposition shown in Fig. 1, alllidif itis desired' topa'sssteam through t e mittmg thesteam` topas'sthrough the cham- `ber 9 andv perforations 18, and to bedistributed over thefa'ces of the bucks,` the steam circulatingthroughboth" bucks when the edal 851s operated. l'f4 the garment is of ilferentthicknesses the' l u per "buck 23; yields toV conform to the erentthickn` ofthe garment by reason ofthebearing parts 39, 40"and39 andV 40.`The f means, just described, lfor operat' the` carriage 24 is notclaimedA herein, as 1t constitutes the subject-matter of my pendingdivisional application Sr.- No. 117,435.
